I tried various suggestion such as setting GPU in Persistence Mode, passing hpet=disable to kernel via grub, updated with latest Dell BIOS and so on. I also ran Dell diagnostic tools and did not found any errors. No errors found in Dell Bios logs. CPU, hdd and GPU all are running at cool temperatures. I also ran memtest (it took entier night) but did not found any ram errors. This happens onece or twice a day (today it happens five times). I'm also attching the bug report as suggested by the tool.

I hope somebody can provide me more suggestions so that I can work peacefully.

So far no solution found. I've now switched to nouveau driver. But, when I need video editing I need real driver. The nouveau has so many limitions. Should I call Dell to replace my GPU card? I'm not sure if this is a driver or hardware problem.

We are still having this problem as well. I've tried all of the new releases of the driver but it persists.

Maybe this is unrelated but I found it peculiar that Dell provides driver version 260.19.29 even though that was a year old at the time of this system's release. Our system has a 3000M and 260.19.29 doesn't even list that as supported. It makes me wonder if Dell recognized this issue and that the newer drivers have this problem.

It appears that this is a common issue with Dell M6500 and 6600 devices. We have few other laptops from Lenovo (thinkpad with NVIDIA 4200M and other nvidia cards). Those seems to working fine. See this thread https://forum.solidworks.com/message...#262573#262573 Tomorrow, I'm gonna try to use device without connected power supply. Otherwise I'm gonna ask dell to replace my card or entire laptop. I can't work like this. I need fix.
